How the Most Famous Royals Got Their Titles

The titles used by members of the royal family may seem complicated, but they actually are supposed to simplify the royal ranking system for the rest of us.

The purpose of titles

How can you tell if the person you’ve just been introduced to is a doctor? The title, “doctor,” is the tipoff. Although you may not know immediately what kind of doctor this person is (say, a medical doctor, a dentist, or a PhD, for example), the “doctor” title tells you, at the very least, that this person has earned an advanced degree in something. Likewise, in Great Britain’s “peerage system,” having a title conveys that one is a “peer of the Royal Realm.” From lowest to highest in terms of ranking, here are the titles available:

Royal titles

Members of the royal family, whether by blood or by marriage, are identifiable by the royal style, “HRH,” short for His/Her Royal Highness. Royals are of a higher status than their non-royal peers. This is true even before a royal holds any other titles. For example, HRH Prince Louis ranks higher in the realm than a non-royal duke (most dukes of the realm are, in fact, non-royal).

Who gets to be a royal

The current set of rules assigning royal title and effectively defining who is and isn’t a royal, was written in 1917 by King George V (the grandfather of Queen Elizabeth II), according to Marlene Koenig, royal expert, who spoke at length with Reader’s Digest about how and why royal titles are conferred. These rules can be modified by the reigning monarch, via legal instruments called “Letters Patent.” For example:

King George VI, the father of Queen Elizabeth II (who was then Princess Elizabeth) issued Letters Patent in 1947 that, among other things, bestowed the following titles on Elizabeth’s soon-to-be husband, Philip Mountbatten: Duke of Edinburgh, Earl of Merioneth, and Baron Greenwich (he wouldn’t acquire the title of “Prince” until 1957). The Letters Patent also made these titles inheritable by Philip’s male heirs.

In 1948, King George VI issued Letters Patent permitting his eldest daughter, then-Princess Elizabeth, to pass the style of “HRH” and “Prince/Princess” onto her children. Prior to this, the daughters of the reigning monarch could be “HRH” and “Princess,” but their children could not. It’s because of these Letters Patent that Charles was “Prince” Charles when he was born.

In 2012, Queen Elizabeth II issued Letters Patent permitting all of Prince William’s children (who are the Queen’s great-grandchildren) to be styled as “HRH” and “Prince/Princess.” Prior to this, only William’s firstborn (George) would have been a Prince. Currently, there is nothing equivalent in place for Prince Harry’s children.

Traditional royal titles and what they tell us

Here’s what some of the royal titles actually tell us about whatever person who goes by that title:

Duke of Cornwall: The eldest son of the reigning sovereign is automatically the “Duke of Cornwall,” which is why Prince Charles has the title, “Duke of Cornwall.” In Scotland, the Duke of Cornwall is referred to as the Duke of Rothesay, a callback to when England and Scotland were separate monarchies.

Prince of Wales: The male heir to the throne is usually created “Prince of Wales” by the reigning monarch. Prince Charles was created “Prince of Wales” by his mum, Queen Elizabeth II, in 1958. When the Prince of Wales becomes King, the “Prince of Wales” title does not automatically transfer to anyone else. It must be granted by the reigning monarch to the next heir apparent. For example, Prince Charles would have to bestow the title, “Prince of Wales” to his son, Prince William.

Earl of Chester: The title, “Earl of Chester” is automatically conferred upon the Prince of Wales when he is given the title, “Prince of Wales.” So Prince Charles is not only HRH The Prince of Wales but also the Earl of Chester.

Duke of York: Traditionally, this is the title given to the second son of the reigning monarch. Prince Andrew, the second son of Queen Elizabeth II, is the Duke of York. When Andrew dies, this dukedom will revert to the Crown because Andrew has no sons, only daughters Princess Beatrice and Princess Eugenie.

Princess Royal: The eldest daughter of a reigning monarch is eligible to be named “Princess Royal” by the reigning monarch. Queen Elizabeth II named her only daughter, HRH The Princess Anne, “Princess Royal.” Elizabeth, herself, was never Princess Royal, despite being the eldest daughter of King George VI because the King’s sister, Princess Mary, was already in possession of the title.

HRH: All children of the reigning monarch are entitled to the style, “HRH,” as are all male-line grandchildren (think: William, Harry, Beatrice, Eugenie). Spouses of the children and grandchildren can be styled “HRH” by the reigning monarch. When Diana and Charles divorced, Diana lost the title of “HRH.” Here’s what else Diana lost in the divorce.

Prince/Princess: Thanks to the Letters Patent of 1917, 1948, and 2012, the children of the monarch, the male-line grandchildren of the monarch, and the children of the Duke and Duchess of Cambridge (William and Catherine) are entitled to go by the title “Prince/Princess.” Prince Harry’s baby-to-be will not be a Prince/Princess, unless the Queen issues Letters Patent to that effect.

Geographical titles: Male-line grandchildren of the reigning monarch are styled by the geographical title of their royal parent. That is why William was HRH Prince William of Wales, Harry was HRH Prince Henry of Sussex, and Prince Andrew’s daughter Beatrice is HRH Princess Beatrice of York. The children of William and Catherine are also styled in this fashion: HRH Princess Charlotte of Cambridge. However, here’s why Harry and Meghan’s children will likely be styled the children of a duke.

Post-divorce: Widows and divorced wives of members of the royal family are styled as [first name, title.] That’s why Diana’s title became “Diana, Princess of Wales” upon her divorce from Prince Charles.

Official titles of current royal family members

Queen Elizabeth II: Elizabeth Alexandra Mary was the firstborn daughter of the Duke and Duchess of York, later King George VI and Queen Elizabeth (later the Queen Mother). She grew up as “HRH Princess Elizabeth of York.” When she married Philip Mountbatten, who had been created as “HRH The Duke of Edinburgh,” she also acquired the title, “HRH The Duchess of Edinburgh.” Upon her father’s death, her title became “Her Majesty, The Queen.” Other titles she holds are “Head of the Commonwealth,” and “Defender of the Faith.” Here is why Her Majesty, The Queen will not be giving up the throne anytime soon.

Prince Philip: Born a prince of Denmark and Greece, Philip Mountbatten renounced his birth-right but was made “HRH The Duke of Edinburgh, Earl of Merioneth, and Baron Greenwich” right before his marriage to Elizabeth in 1947, who was not yet Queen. He was made “Prince Philip” in 1957. Here is why Prince Philip is not “King Philip”.

Prince Charles: Charles was born “HRH Prince Charles Philip Arthur George” and later was created “HRH The Prince of Wales, Earl of Chester.” The press and the public usually refer to him as “Prince Charles,” which isn’t his title, but is technically not incorrect either—because blood princes/princesses are styled with their own name alongside the title of prince/princess. Charles is also “HRH The Duke of Cornwall”, and when in Scotland, “HRH The Prince Charles, Duke of Rothesay” (this is the one instance when Charles is styled by his Christian name).

Camilla: When Camilla married Charles, she technically became “HRH The Princess of Wales” (although she doesn’t use this title) and is also styled as “HRH The Duchess of Cornwall,” and when in Scotland, “HRH The Duchess of Rothesay.” She is also, technically, “HRH The Princess Charles,” but not “Princess Camilla”—because princesses by marriage are styled by their husband’s name, as opposed to their own, which is reserved for blood princesses (such as “HRH Princess Eugenie”). That’s why even though the press and public have always referred to Diana as “Princess Diana,” she was never actually “Princess Diana” but rather “HRH The Princess of Wales,” and upon her divorce, “Diana, Princess of Wales.” Here are some things you didn’t know about Camilla.

Prince William: Born “HRH Prince William Arthur Philip Louis of Wales,” he was made “HRH The Duke of Cambridge, Earl of Strathearn, and Baron Carrickfergus” on his marriage to Catherine, and is styled as “HRH The Duke of Cambridge.” The press and the public call him “Prince William” for short, which isn’t his title, but is technically not incorrect either.

Catherine: When she married William, she technically became “HRH Princess William,” but she is styled as “HRH The Duchess of Cambridge, Countess of Strathearn, and Lady Carrickfergus.” Although the press and the public often refer to Catherine as variations on “Catherine, Duchess of Cambridge,” her first name is not part of her title, and it would only ever become part of her title if she were to become divorced or widowed.

George, Charlotte, and Louis: Thanks to the Queen’s Letters Patent of 2012, her great-grandchildren from her grandson, William, were all born “HRH Prince/Princess [first name] of Cambridge.”

Prince Harry: Born “HRH Prince Henry Charles Albert David of Wales,” he was styled before his marriage as “HRH Prince Henry of Wales” and has always been referred to by the public and the press as “Prince Harry.” Upon his marriage, the Queen also made him “HRH The Duke of Sussex, Earl of Dumbarton, and Baron Kilkeel.”

Meghan: On her marriage to Harry, she became “HRH The Duchess of Sussex.” If Harry had not been granted a dukedom, Meghan would have had the title “HRH Princess Henry of Wales.”

the eldest son of the sovereign is the Duke of Cornwall (for England) established by royal charter in 1337) and in Scotland as the Duke of Rothesay. These titles are automatic. Act of Union in 1707 established Great Britain — prior to this, England and Scotland were separate monarchies, but with the death of Elizabeth I, James VI, great-great grandson of Henry VII, succeeded his kinswoman, Elizabeth I, reigning in both countries. James I in England. In 1707 became one monarchy. In 1801, the KIngdom of Great Britain and the Kingdom of Ireland were united as the United Kingdom of Great Britain and Ireland. (Now Northern Ireland).

The male heir to the throne is usually named Prince of Wales and earl of Chester. The POW takes precedence for styling

Other children of the sovereign are styled as HRH The Prince or HRH The Princess christian name and nothing else if there are no dukedoms, etc .. HRH The Prince Andrew, HRH The Princess Anne.

However, sons of the sovereign usually receive a dukedom.. Children of royal dukes (who are the sons of the sovereign) are styled by the geographical title — HRH Prince William of Wales. HRH Princess Charlotte of Cambridge. Princess Beatrice of York.
